Description

Technical Field

[0001] The invention relates to the field of earphones, and in particular to a wind-noise-proof earphone and a windproof sticker thereof. Background Art

[0002] Headphones are a pair of conversion units that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers close to the ears. When you wear open headphones on a windy street, since wind is a complex and variable noise source, even if the headphones are equipped with call noise reduction technology, they can rely on microphones to capture environmental noise and eliminate these noises through algorithm processing. However, in strong wind conditions, it is difficult to effectively eliminate all wind noise with current algorithms, so you may still hear whistling during a call, which is actually normal and not a problem with the headphones themselves.

[0003] When using Bluetooth headsets for calls, wind noise often becomes a distraction. The direction and strength of the wind may affect the call quality of the headset. Especially outdoors, the impact of wind may make your voice unclear, affecting the call quality or listening experience. For this reason, users generally try to adjust the angle or position of the headset to reduce the chance of wind blowing directly to the microphone. Although the impact of wind noise can be reduced, it still brings inconvenience to the use of the headset. Therefore, it is necessary to improve the existing headset. Summary of the invention

[0004] In view of this, the present invention aims at the deficiencies in the prior art, and its main purpose is to provide a wind-noise-proof headset and a wind-proof patch thereof, which can effectively solve the problem that the existing headset is easily affected by wind noise, resulting in poor call quality and listening experience of the headset.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A windproof patch includes a first windproof layer and a second windproof layer. The second windproof layer is stacked and fixed on the inner wall surface of the first windproof layer through a first adhesive layer. The inner side surface of the second windproof layer and the inner wall surface of the first windproof layer form a sound input cavity. The second adhesive layer is arranged on the inner wall surface of the second windproof layer.

[0007] As a preferred solution, both the first adhesive layer and the second adhesive layer are double-sided adhesives.

[0008] As a preferred solution, the first windproof layer and the second windproof layer are both made of EVA material.

[0009] As a preferred solution, the thickness of the first windproof layer and the second windproof layer are both 1.0 mm.

[0010] As a preferred solution, the sound input cavity includes a buffer section and a sound input section which are sequentially connected from top to bottom.

[0011] As a preferred solution, a release paper is bonded and fixed to the second adhesive layer.

[0012] As a preferred solution, the release paper has an easy-tear portion extending outwardly.

[0013] A wind noise proof headset comprises a shell and the aforementioned windproof sticker, wherein a microphone hole is provided on the shell, the windproof sticker is attached to the shell through a second adhesive layer and covers the microphone hole, the inner side surface of the second windproof layer, the inner wall surface of the first windproof layer and the surface of the shell form the aforementioned sound input cavity, the opening of the sound input cavity is vertically downward, and the microphone hole is connected to the sound input cavity.

[0014] As a preferred solution, a positioning groove is concavely provided on the shell, the microphone hole is opened on the end face of the positioning groove, and the windproof sticker is attached to the positioning groove through the second adhesive layer and covers the microphone hole.

[0015] As a preferred solution, the microphone hole is connected to the sound input section.

[0016] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0017] The second windproof layer is stacked and fixed on the inner wall surface of the first windproof layer through the first adhesive layer, and the second adhesive layer is arranged on the inner wall surface of the second windproof layer. When the windproof sticker is adhered to the earphone shell, the windproof sticker covers the microphone hole, and the inner side surface of the second windproof layer, the inner wall surface of the first windproof layer and the surface of the shell form the aforementioned sound input cavity. When wind noise comes, the windproof sticker protects the microphone hole on the inside, and most of the wind noise energy will be blocked, reflected or absorbed by the first windproof layer. When the person wearing the earphone talks, the sound waves can be transmitted to the microphone hole through the sound input cavity of the windproof sticker, which will not affect the normal voice reception. The installation is simple and can be used selectively according to personal requirements for wind noise. It is also suitable for various types of earphones.

[0032] Please refer to Figures 1 to 5 As shown, it shows the specific structure of a preferred embodiment of the present invention, including a shell 10 and a windproof sticker 20.

[0033] The housing 10 is provided with a microphone hole 11. In the present embodiment, the housing 10 is provided with a positioning groove 12. The microphone hole 11 is provided at an end surface of the positioning groove 12. The depth of the positioning groove 12 is greater than 0.3 mm.

[0034] The windproof sticker 20 includes a first windproof layer 21 and a second windproof layer 22, the second windproof layer 22 is stacked and fixed on the inner wall surface of the first windproof layer 21 through a first adhesive layer 23, the inner side surface of the second windproof layer 22 and the inner wall surface of the first windproof layer 21 form a sound input cavity 24, the inner wall surface of the second windproof layer 22 is provided with a second adhesive layer 25, the windproof sticker 20 is attached to the outer shell 10 through the second adhesive layer 25 and covers the microphone hole 11, specifically, the inner side surface of the second windproof layer 22, the inner wall surface of the first windproof layer 21 and the surface of the outer shell 10 form the aforementioned sound input cavity 24, the opening of the sound input cavity 24 is vertically downward, and the microphone hole 11 is connected to the sound input cavity 24; in the present embodiment, the first adhesive layer 22 and the second adhesive layer 25 are both double-sided adhesives, and the first windproof layer 21 The first windproof layer 21 and the second windproof layer 22 are both made of EVA material, and the thickness of the first windproof layer 21 and the second windproof layer 22 are both 1.0 mm; in addition, the sound input cavity 24 includes a buffer section 241 and a sound input section 242 which are connected in sequence from top to bottom, and the microphone hole 11 is connected to the sound input section 242. The design of the buffer section 241 ensures that after the wind noise enters the sound input cavity 24 from the opening, it does not directly enter the microphone hole 11 after passing through the sound input section 242, but a part of the wind noise enters the buffer section 241 through the sound input section 242. This part of the wind noise will be weakened after a series of reflections in the buffer section 241 before entering the microphone hole 11. This design further reduces the wind noise; it should be noted that before the windproof sticker 20 is assembled with the outer shell 10, a release paper 26 is bonded and fixed to the second adhesive layer 25 to prevent dust and other debris from adhering to it. As a result, the adhesion of the second adhesive layer 25 is insufficient, and the release paper 26 extends outward to have an easy-to-tear portion 261; and the windproof sticker 20 is attached to the positioning groove 12 through the second adhesive layer 25 and covers the microphone hole 11. The inner side surface of the second windproof layer 22, the inner wall surface of the first windproof layer 21, the surface of the outer shell 10 and the end surface of the positioning groove 12 together form the aforementioned sound inlet cavity 24.

[0035] The production process of this embodiment is described in detail as follows:

[0036] First, tear off the release paper 26, and then stick the windproof sticker 20 on the end face of the positioning groove 12, so that the inner side surface of the second windproof layer 22, the inner wall surface of the first windproof layer 21, the surface of the outer shell 10 and the end face of the positioning groove 12 together form the sound inlet cavity 24.

[0037] The design focus of the present invention is: the second windproof layer is stacked and fixed on the inner wall surface of the first windproof layer through the first adhesive layer, and then the second adhesive layer is arranged on the inner wall surface of the second windproof layer. When the windproof sticker is adhered to the earphone shell, the windproof sticker covers the microphone hole, and the inner side surface of the second windproof layer, the inner wall surface of the first windproof layer and the surface of the shell form the aforementioned sound input cavity. When wind noise comes, the windproof sticker protects the microphone hole on the inside, and most of the wind noise energy will be blocked, reflected or absorbed by the first windproof layer. When the person wearing the earphone talks, the sound waves can be transmitted to the microphone hole through the sound input cavity of the windproof sticker, which will not affect normal voice reception. The installation is simple and can be used selectively according to personal requirements for wind noise. It is also suitable for various types of earphones.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
